生鲜配送系统是一个复杂的电子商务解决方案，需要处理订单管理、库存控制、配送路线规划、冷链物流跟踪等多个环节。以下是一个简化的生鲜配送系统核心功能模块的代码框架示例：
1. 系统架构概述
```python
系统主要模块
class FreshDeliverySystem:
def __init__(self):
self.inventory = InventoryManager()
self.orders = OrderManager()
self.delivery = DeliveryManager()
self.customers = CustomerManager()
self.payments = PaymentProcessor()
```
2. 库存管理模块
```python
class InventoryManager:
def __init__(self):
self.products = {} {product_id: {name:..., quantity:..., expiry_date:...}}
def add_product(self, product_id, name, quantity, expiry_date):
self.products[product_id] = {
name: name,
quantity: quantity,
expiry_date: expiry_date,
price: 0 可以从数据库获取
}
def update_quantity(self, product_id, quantity_change):
if product_id in self.products:
self.products[product_id][quantity] += quantity_change
检查是否过期或库存不足
self._check_inventory_health()
def _check_inventory_health(self):
实现库存健康检查逻辑
pass
```
3. 订单管理模块
```python
class OrderManager:
def __init__(self):
self.orders = []
def create_order(self, customer_id, items):
"""
items: list of (product_id, quantity) tuples
"""
order = {
order_id: self._generate_order_id(),
customer_id: customer_id,
items: items,
status: pending,
delivery_time: None,
total_price: 0
}
self.orders.append(order)
return order[order_id]
def update_order_status(self, order_id, status):
for order in self.orders:
if order[order_id] == order_id:
order[status] = status
return True
return False
def _generate_order_id(self):
实现订单ID生成逻辑
pass
```
4. 配送管理模块
```python
class DeliveryManager:
def __init__(self):
self.routes = {}
def assign_delivery(self, order_id, delivery_person_id):
简单的配送分配逻辑
route = self._calculate_route(order_id)
self.routes[order_id] = {
delivery_person_id: delivery_person_id,
route: route,
status: assigned
}
def _calculate_route(self, order_id):
这里可以集成地图API或路径规划算法
简化版返回固定路线
return [
{address: 仓库, time: 08:00},
{address: 客户地址, time: 10:00}
]
def track_delivery(self, order_id):
返回配送实时状态
if order_id in self.routes:
return self.routes[order_id]
return None
```
5. 客户管理模块
```python
class CustomerManager:
def __init__(self):
self.customers = {}
def register_customer(self, customer_id, name, address, contact):
self.customers[customer_id] = {
name: name,
address: address,
contact: contact,
preferences: {} 饮食偏好等
}
def get_customer(self, customer_id):
return self.customers.get(customer_id)
```
6. 支付处理模块
```python
class PaymentProcessor:
def process_payment(self, order_id, amount, payment_method):
集成支付网关如支付宝、微信支付等
简化版只返回成功状态
return {
status: success,
transaction_id: txn_ + str(order_id),
amount: amount
}
```
7. 主业务流程示例
```python
def main_process():
system = FreshDeliverySystem()
添加产品到库存
system.inventory.add_product(p001, 有机苹果, 100, 2023-12-31)
system.inventory.add_product(p002, 新鲜三文鱼, 50, 2023-11-15)
注册客户
system.customers.register_customer(c001, 张三, 北京市朝阳区, 13800138000)
创建订单
order_id = system.orders.create_order(c001, [(p001, 5), (p002, 2)])
处理支付
payment = system.payments.process_payment(order_id, 250.00, alipay)
分配配送
system.delivery.assign_delivery(order_id, d001)
更新订单状态
system.orders.update_order_status(order_id, processing)
跟踪配送
delivery_status = system.delivery.track_delivery(order_id)
print(f"配送状态: {delivery_status}")
if __name__ == "__main__":
main_process()
```
实际开发建议
1. 技术栈选择：
- 后端：Python (Django/Flask), Java (Spring Boot), Node.js
- 前端：React/Vue.js
- 数据库：MySQL/PostgreSQL (关系型) + MongoDB (文档型)
- 实时功能：WebSocket/Socket.IO
- 地图服务：高德/百度/Google Maps API
2. 关键功能实现：
- 冷链物流监控（温度传感器集成）
- 智能路径规划算法
- 实时订单跟踪
- 库存预警系统
- 客户偏好分析
3. 安全考虑：
- 支付安全（PCI DSS合规）
- 数据加密
- 用户认证与授权
完整实现一个生产级的生鲜配送系统需要数千行代码和多个开发人员的协作。上述代码仅为概念性框架，实际开发需要根据具体业务需求进行扩展和完善。
